摘要
在铁电体的慢极化颠倒的时间间隔薄电影在超过二十年被拓宽违背古典 Kolmogorov Avrami Ishibashi (KAI ) 应用的地走近领域切换的强制的地的方程。在这个方程的颠倒的领域成核的对数的等待的时间的 Lorentzian 分布的假设能解决这窘境。在我们的工作，我们在薄电影从强制电压的分发解释这个方程，并且导出类似的功能从长期的印记效果而非 KAI 模型的考虑描述慢极化颠倒。
Time interval of slow polarization reversal in ferroelectric thin films is broadened over more than two decades to disobey the classical Kolmogorov-A vrami-Ishibashi （KAI） equation as the applied field approaches the coercive field of domain switching. The assumption of a Lorentzian distribution of logarithmic waiting times of reversed domain nucleation in this equation can resolve this dilemma. In our work, we explain this equation from the coercive-voltage distribution in thin films, and derive a similar function to describe slow polarization reversal from the consideration of a long-time imprint effect rather than the KAI model.
